Recovery Vmfs -

First, unmount the datastore (force if necessary).

Once the partition is recreated, attempt the mount again: recovery vmfs

The Virtual Machine File System (VMFS) is incredibly resilient, but it isn't invincible. The good news? You just need to know the right commands and the right order of operations. First, unmount the datastore (force if necessary)

We’ve all been there. You log into vCenter, click on a datastore, and your heart sinks. Instead of the happy green "Normal" status, you see "Not Mounted" or "Corrupted." Maybe an ESXi host lost power during a SAN firmware update, or someone accidentally deleted a LUN mapping. You just need to know the right commands

vmkfstools -V -r /vmfs/devices/disks/naa.6000c29c4c5a2b1c:1 If the metadata is corrupt (files show up, but VMs won't power on), you need the VMFS Offline Metadata Analyzer ( voma ).

esxcfg-scsidevs -l Look for the device with the correct size and LUN number that does not have a filesystem label next to it. Now, we attempt a manual mount. Use the -r flag for read-only to ensure we don't make the situation worse.

Stay calm. Run esxcfg-scsidevs . Use vmkfstools -V . And whatever you do,
